As reported earlier, a homemade bomb was found in front of Perintis Farma pharmacy on Jl. Pahlawan No.83, Tegalrejo district, Magelang, on Tuesday morning. The bomb was put inside a brown women's handbag and placed under a cart belonging to a batagor (fried fish dumpling) vendor.

Condro confirmed that the bomb circuit contained ammunition; however, it failed to explode as the batteries in the circuit malfunctioned.

"We are asking local administrations to install CCTVs in strategic places. It is also hoped that business owners install CCTVs both inside and outside of their buildings," said Condro.

The police chief said Perintis Farma's owner only had CCTVs installed inside the building. "So, the person who placed the bomb in front of the pharmacy cannot be seen [in the recording]," said Condro.

Central Java Police spokesperson Sr. Comr. Djarod Padakova said earlier that the police bomb squad (Jihandak) disposed of the bomb, which had a piece of paper with messages written in Arabic characters inside, on the day it was found. Pieces of the disposed bomb were collected for a further investigation discover the type of the explosives it contained.

"On whether it's a high- or low-grade explosive, the police's Indonesia Automatic Fingerprint Identification System [Inafis] is still examining it," said Djarod.
